Must the SKU of ShipOut system be the same as that of the selling channel?

The ShipOut system SKU can be set to be the same as or different from the store SKU. After the product is created, all products need to be associated with the store SKU through the mapping alias. After successful association, whether the system SKU is the same as the store SKU or not, the system can identify the product.
